What is Yule Walker equation in time series?

The Yule-Walker equations provide a straightforward connection between the AR model parameters and the covariance function of the process. In this paper, we propose a nonlinear extension of the AR model using kernel machines.

What are Yule-Walker equations used for?

The autoregressive model parameters are obtained from the autocovariance of the time series by solving a system of linear equations. The Yule-Walker equations provide a straightforward means to estimate an autoregressive model from data.

What is Walker equation?

8] stated that γ is expected to be low for materials with low ductility and proposed the following equation to determine the Walker parameter: γ = 0.5 ± S T − σ Y S T + σ Y. (6)
